10 Technical Data and Conformity | 10.2 Installation Requirements ZEISS
Parameter Requirement
Stability 0.5 °C/10 min
Heat dissipation 1 kW
Connection hose 8 mm inside diameter. One 25 m roll is delivered with the microscope.
Instrument con-
nection Quick exchange connectors. Two are delivered with the microscope.
Nitrogen
Gaseous dry nitrogen is used to vent the specimen chamber during specimen exchange. The nitro-
gen can be taken either from a gas cylinder or from an in-house supply system.
The connection must be equipped with an appropriate pressure reducer and a shut-off valve that
is secured against accidental re-activation.
Parameter Requirement
Flow rate Approx. 40 l/min for ventilation of specimen chamber with chamber
door open
Pressure 0.30–0.35 MPa (3.0–3.5 bar)
Quality 4.6 with nitrogen content > 99.996 %
Connection hose 6 mm inside diameter. 10 m are delivered with the microscope.
Parameter Requirement
Flow rate Approx. 3 l/min for ventilation of specimen chamber with chamber
door open
Pressure 0.2–3.3 bar
Quality 4.6 with nitrogen content > 99.996 %
Connection hose 4 mm inside diameter. 10 m are delivered with the microscope.
Instrument con-
nection Quick exchange connector. One is delivered with the microscope.
Compressed Air
Compressed air is used to operate several valves and the auto leveling system.
The necessary compressed air can be either generated by a compressor (part no.
345596-0000-000) or taken from a gas cylinder or from an in-house supply system.
The connection must be equipped with an appropriate pressure reducer and a shut-off valve that
can be secured against accidental re-activation.
Parameter Requirement
Typical flow rate Approx. 12 l/min at 0.6 MPa pressure during air leveling system infla-
tion
Pressure 0.6–0.8 MPa (6–8 bar)
Quality Oil-free
Connection hose 6 mm inside diameter. 10 m are delivered with the microscope.
